Poster Dog..good idea, or bad idea?

If we could get permission from one owner who's dog was devistatingly thin, we could use him/her as a poster dog.

So we focus firstly on feeding this dog and report the progress of him/her and take pictures and if we get a website, or put a brochure together we could include the stories and everything. Maybe that could get some attention to our group? How we saved one dog's life and everything?
Just a thought, what's everyone elses opinio on this?
